1. Field of the Invention
The present invention relates generally to a child-seat for automotive vehicles. Particularly, the present invention relates to a child-seat which can be withdrawably accommodated in a concave space in a bench-type automotive seat.
2. Description of the Related Art
Various types of child seats for automotive vehicles have been proposed for promoting increased safety for young children being transported by car, bus, etc. Generally, such child seats are constructed for restraining and protecting a child seat thereon. Recently, so-called `built-in` child seats which are permanently installed in a bench seat of an automobile or the like, have been popular for providing highly stable seating for child passengers.
For example, one such previously proposed built-in child seat has been disclosed in. Japanese Patent Application No. 56-28023. This document teaches a child seat built-in to a rear passenger bench seat of an automobile at a center, arm rest position. The seat unfolds from the seat back of the bench seat. The built-in nature of the seat promotes ease of use and since in may be folded within the seat back of the vehicle when not in use, no storage problem is presented when the child seat is not used.
However, such conventional, built-in child seats may be susceptible to swinging motion (laterally applied force) during turning etc., further, such conventional arrangements do not seek means for stabilizing a child's legs and feet. Also, the cushion and safety pad portions of such conventional seats are attached by a pair of hinges, however, greater lateral stability than can be provided by such arrangements has been desired.
In addition, such conventional built-in child seats are arranged such that, in an unfolded condition, the seat cushion of the child seat is positioned suspended above the seat cushion of the vehicle seat. Thus, the seat cushion of the child seat is susceptible to a tendency to swing back and forth in response to lateral G forces generated in vehicle cornering, and the like.
Other factors which are desirable in child-seating for moving vehicles are increased stability in a back support for child seats and adjustability for accommodating different builds of various children, or to compensate for a child's growth while still using such a vehicular child seat.
Thus is has been required to provide a built-in child seat for an automotive vehicle with simple easy to use structure which provides stable support when in use, including substantial stability against laterally applied forces.
It is therefore a principal object of the present invention to overcome the drawbacks of the related art.
It is a further object of the present invention to provide a child seat having increased stability and adjustability for accommodating different or growing children.
It is also an objection of the invention to provide a built-in child seat for an automotive vehicle having a simple structure which may provide stable support when in use, including substantial stability against laterally applied forces.
In order to accomplish the aforementioned and other objects, a built-in child seat for an automotive vehicle is provided, comprising:
In the drawings:
FIG. 1; is a schematic perspective view of a preferred embodiment of a child seat according to the invention showing an unfolded state of the seat;
FIG. 2 is a schematic perspective view of the child seat of FIG. 1 in a retracted state;
FIG. 3 shows a perspective view for explaining a process of unfolding the child seat of the invention, from the state shown in FIG. 2, to that of FIG. 1; and
FIG. 4 is an enlarged cross-sectional view of a belt portion of the child seat of the invention for illustrating operation of a belt length adjusting means thereof.
Referring now to the drawings, a built-in child seat according to the invention will be described hereinbelow in detail.
FIGS. 1 to 4 show a preferred embodiment of a built-in automotive child seat (hereinbelow: child seat) according to the invention. The child seat 10 is installed in a vehicular bench seat 1, usually a rear seat of a passenger vehicle, or the like. The bench seat includes a seat cushion 2 and, at a center of the seat back 3 of the bench seat 1, a recess 4 is provided. The child seat 10 according to the invention is arranged to fold into and be unfolded from the recess 4.
The child seat 10 comprises a seat cushion 11 which may be folded pivotally up and down to act as a seat cushion when the child seat is unfolded and a bottom side of the seat cushion 11 acts as a cover for the child seat 10 when in a folded condition. When the child seat 10 is unfolded, such as pictured in FIG. 1, a rear wall of the recess 4 acts as a child seat back 4a. Two wing portions 12, 12 are disposed at seat side of the seat cushion 11 such that, a child seated in the child seat 10 is firmly held at each side thereof between the wings 12, 12. Further, as seen in FIG. 8, when the child seat 1 is unfolded, a child seat therein will rest against the child seat back 4a, which is formed by the rear wall of the recess, thus the adjoining seat back 8 of the bench seat 1 at each side thereof further serve to nestle the child firmly in the seat and thus the child is substantially protected from lateral G forces which may occur during cornering, etc. It will be noted from the drawing that side cushion members 4b, 4b are formed on inner side walls of the recess 4 for enhancing the comfort of the recessed child seat 10. It will be noted that, according to the above description, the single seat cushion 11 may be folded down from the seat back 8 of the bench seat 1 and thus quickly and simply provides a recessed child seat 10 wherein the two wings 12, 12 and the side cushions 4b, 4b collectively act to comfortably retain the sides of the body of a seat occupant. Thus a child seat having high security and protection against lateral G forces may be provided at low cost.
It will also be noted that, in the unfolded condition, the seat cushion 11 of the child seat 10 is stably positioned atop the seat cushion 2 of the bench seat. Thus, the seat cushion 11 of the child seat resists a tendency to swing from side to side during cornering of the vehicle, or the like.
Further, the child seat 10 according to the invention may also be provided with a substantially T-shaped chest pad 15 which, as may be seen by comparing FIGS. 1-3, is disposed on a rotatable hinge pin 16 in such a way as to be interlocked with the seat cushion 11 and to be pivotably mounted so as to rotate upwardly to form a chest pad 15. The lower cut-out portions defining the T-shape act in conjunction with the V-shape of the interlocking end of the seat cushion 11 so as to define spaces for snugly retaining the upper legs of a child occupying the child seat 10.
The chest pad 15 has insert openings 17, 17 at a top side thereof for receiving belts 20, 20 therethrough. Mounting tongues 18, 18 are provided at point end portions of each of the belts 20, 20 for being received by the insert openings 17, 17.
In order to further improve the utility of the invention, the child seat 10 is provided with belt adjusting means, as will be explained hereinbelow with reference to FIG. 4.
As may be seen in FIGS. 3 and 4, the child seat back 4a is provided with a pair of grooves formed therethrough and having a stepped, elongate configuration for allowing the belts 20, 20 to be set at a desired height depending on the size of the child seat occupant.
Further, provided in a space behind the child seat back 4a, a pair of spring retractable roll-type belt mountings 33, 33 are provided, the belts being wound around the belt mountings 33, 33 and held by a locking member 32 which may be manually released by a lever 31 mounted at an upper side of the seat back 3 of the bench seat. According to the present embodiment, the lever is provided at a position substantially above the recess 4.
Thus, according to actuation of the lever 31, a the lock member 32 is released and a desired length of the belt 20 may be extracted for establishing a comfortable fit for a child to occupy the seat. Then, when the lever 31 is released, the lock member closes to firmly hold the belt 20 in place at the desired length. According to the above-described structure, a child may be held on a highly stable seat cushion 11 while gently but firmly being held on all sides by the wings 12, 12, the side cushions 4b, 4b, the chest pad 15 and the child seat back 4a.
Thus, a secure built-in child seat with high security against lateral G forces with simple construction and operability may be provided at low cost.
While the present invention has been disclosed in terms of the preferred embodiment in order to facilitate better understanding thereof, it should be appreciated that the invention can be embodied in various ways without departing from the principle of the invention. Therefore, the invention should be understood to include all possible embodiments and modification to the shown embodiments which can be embodied without departing from the principle of the invention as set forth in the appended claims.
